泄洪闸闸墩施工期温控目的在于降低混凝土早期水化热,闸墩结构中水管冷却方法应用较少。本文结合某水库溢洪道闸墩温控实例,通过对水管冷却的热工计算,对比相同施工环境条件下是否采用冷却水管的实际温度变化过程,表明在泄洪闸闸墩施工期温度控制中使用水管冷却可有效降低混凝土温度峰值,对闸墩结构的温控与防裂的实践意义重大。 Flood control sluice pier construction temperature control aims to reduce the early concrete hydration heat, pier structure of the water pipe cooling method used less. In this paper, a reservoir spillway pier temperature control example, through the thermal calculation of water pipe cooling, compared with the same construction conditions whether the actual use of cooling water pipe temperature changes, that the sluice gate pier construction temperature control using water pipe cooling Can effectively reduce the peak temperature of concrete, the pier structure of the temperature control and crack prevention practice of great significance.
